Error 429 too_many_request in win10-portable.exe after upgrade. thx

I got the problem that encryption on android is different from that of the win-portable.
the android version seems is most update (as update is forced).
so I browse the forum and told to update the win-portable,
from the above version to the above 2nd mentioned version.

  1. it asked me to update the master key?
  2. it asked me to re-encrypt the entries?

I think i should have done both.
yet before the 2nd step, these errors already show up.
